Abstract
The utility model relates to a kind of composite material bus body, is particularly useful for the application of New energy electric passenger vehicle.Vehicle body is made up of upper vehicle body, under body, upper vehicle body is made up of car roof and column bonding pad, car roof and column bonding pad are an integral structure, under body comprises gusset, forward and backwardly to enclose and floor, gusset, forward and backwardly to enclose and floor is an integral structure, the column bonding pad of upper vehicle body connects by being connected band plate with the gusset of under body, forms bus body.The utility model is made up as the composite material of reinforcement of glass fibre (or carbon fiber etc.) and fabric thereof, compared with metal body, when meeting usage condition, composite-material body has obvious loss of weight advantage, can loss of weight more than 35%, also there is excellent corrosion stability, corrosion stability and heat-proof quality, because weight saving can reduce energy resource consumption greatly, for automobile lightweight provides new technological approaches.
Description
Technical field
The utility model relates to a kind of composite material bus body, is particularly useful for the application of New energy electric passenger vehicle.
Background technology
Current bus body is generally made up of the metallic material such as steel, aluminum alloy.Steel body has the shortcomings such as own wt is large, poor corrosion resistance; It is not obvious that car body of aluminum alloy has weight loss effect, high in cost of production shortcoming; The shortcomings such as it is various that metal body has parts on the whole, and assembly process is numerous and diverse.
Summary of the invention
The purpose of this utility model is to provide that a kind of tare is light, the simple composite material bus body of assembly process.
The technical solution of the utility model is: vehicle body is made up of upper vehicle body, under body, upper vehicle body is made up of car roof and column bonding pad, car roof and column bonding pad are an integral structure, under body comprises gusset, forward and backwardly to enclose and floor, gusset, forward and backwardly to enclose and floor is an integral structure, the column bonding pad of upper vehicle body connects by being connected band plate with the gusset of under body, forms bus body.
Arrange column between described upper vehicle body and under body, one end of column is connected with the column bonding pad of upper vehicle body by connecting band plate, and the other end of column connects by being connected band plate with the gusset of under body, forms bus body.
The utility model has the advantages that: the vehicle body that the utility model adopts glass fibre (or carbon fiber etc.) and fabric thereof to make as the composite material of reinforcement, the material of high-strength light makes product weight decline to a great extent, add corrosion stability, fatigue durability and heat-proof quality that resin is excellent, can be used for replacing existing metal body.Compare steel body weight and reduce more than 35%, there is withstanding corrosion, endurance, the heat insulation and advantage such as ease of maintenaince simultaneously.Under body of the present utility model is integrated with the function on day bus chassis, simple relative to day bus assembly process, does not need welding tooling and large-scale assembly tooling.
Accompanying drawing explanation
Fig. 1 is composite material bus body.
Fig. 2 is composite material coach body structure layout.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Vehicle body is made up of upper vehicle body 1, under body 2, upper vehicle body 1 is made up of car roof 3 and column bonding pad 4, car roof 3 and column bonding pad 4 are an integral structure, under body 2 comprises gusset 5, front wall 6, back wall 7 and floor 8, gusset 5, front wall 6, back wall 7 and floor 8 are an integral structure, the column bonding pad 4 of upper vehicle body 1 connects with the gusset 5 of under body, forms bus body.
Arrange column 9 between described upper vehicle body and under body, one end of column 9 is connected with the column bonding pad 4 of upper vehicle body by connecting band plate, and the other end of column 9 connects by being connected band plate with the gusset 5 of under body, forms bus body.
Get off as full-bearing type integral structure, adopt low floor vehicle body structure layout, and be integrated with that the function such as chassis and floor is front-rear axle, front/rear collision bumper and chaufeur platform provide installing space, at corresponding connection location pre-embedded steel slab to strengthen bonding pad, and solve the detachable requirement of the parts such as battery box.Get on the bus as integral structure, make connecting struts in sash position and be connected with window pillar, and make the sagging mounting glass that is used in window area.Window pillar is used for connecting upper and lower vehicle body.
This composite material bus body mainly comprises upper and lower vehicle body, column.
Its manufacturing process and method as follows:
1) prepare under body: foamed sandwich structure, adopt VARI technological forming, material is glass woven fabric+carbon cloth+foam sandwich+resin, and join domain buries the built-in fittings such as steel plate underground for strengthening bonding pad and providing connection location;
2) vehicle body in preparation: foamed sandwich structure, adopt VARI technological forming, material is glass woven fabric+foam sandwich+resin;
3) prepare window pillar: compression molding, material is glass fibre and carbon fiber prepreg;
4) assemble upper and lower vehicle body: upper and lower vehicle body by after tool locating, by window pillar respectively with it being bolted to and getting on and off.
Detailed description of the invention described in the utility model is not in order to limit the utility model; a just more excellent practical case of the present utility model; all make within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
